Scripttale is the name of the au. Update!Sans is from an au where the player got so incredibly bored that they gave Sans the power to change the code at will. However he didn’t realize this and the player did a genocide run but once they made it to they started fighting Sans instead of saying “a massive anomaly in the time space continuum” it instead said “an enormous anomaly in the time space continuum”. The player ignored this and killed Sans. At least that’s what they thought because right before he turned to dust he remembered that he only ever used one eye for his magic. In an attempt to try it he activated the abilities the player gave him. While he was confused and panicking he saw code that said his hp was at 0 so he tried changing it because he had no other way to try to save himself. He managed to change it to 1. Once he did that he stopped dusting and fully healed. The player also realized that they don’t have 20 lv. Now that he wasn’t dying he calmed down and looked at even more code. He saw that there was many codes that seemed like things that would be in video games. He saw a switch that said “Memory of Resets” he flicked it on and remembered everything that has happened. This also made him realize that he is in a video game. He then decides to make the player not able to reset. He then goes and encounters them before they got rid of the world. He appeared in charas place and reminded the human about everything they’ve done. After a long talk he starts the battle with new attack patterns. He started using orange bones and karma damage and actual damage seemed to be increased but the human didn’t bother checking. The human also noticed that sans was not getting tired from all of these new attacks. He eventually managed to kill the human and player. Once he beat them he decided to revive all of his friends and his brother Papyrus. He also figured out that the player was controlling the human the whole time. He ended up reviving the human and got rid of the players control. Frisk gained their control back over their own body and thanked sans. After that he continued exploring the code until he figured out how to go to different au’s and found plenty of iconic aus. The first of these was US which he hadn’t thought about how bad it could be if he got spotted or changed anything in the timeline. Ofc he saw US sans and went to say hi. They had a nice chat but he eventually realized he might have changed the time line and had to go back in time to where he previously was before getting spotted. He didn’t realize that this still changed the timeline and led to its own new timeline. Later while exploring he met OT sans and they had a chill talk about more serious things like the resets and the other AUs. Update decided not to delete OT sans’ memory in exchange for not telling anyone else in the timeline. Due to this OT sans no longer forgot resets after learning how they work. Update left and ended up in the ULB timeline. Update realized that ULB sans’ fate was done for so he told him to at least try to be funny before you die and put it on your first breath instead of last breath. This suprisingly created a new timeline. Update left and went to EpicTale instead. Here he saw the insane fights that were happening and in order to change things he made Epic Gaster unable to reset(yes i made my guy responsible for that ). He would leave there and come back later but first he saw that he could go to a place called “The DoodleSphere” which wasn’t named like all the others so he went there. This is where he met Ink.They had a talk about the aus and how Update was a new one and also an overpowered one. He also mentioned about how Update had change the timeline of almost every place he went on accident. Error who had been listening secretly heard this and instantly came over in order to stop Update, knowing he would create more chaos then there already was. They started to fight each other and Error could do literally nothing. Update had already changed the code so that error couldn’t hurt him. Instead of leaving error with no response he made a deal with him that Update would try to be more careful when it comes to certain universes. Error didn’t have much of a choice other then to accept. After that Update left the doodlesphere in order to find someone who was similar to him aka file aware. Eventually he found file aware who was extremely similar to update but file aware couldn’t remember his brother. Both of them were suspicious of each other so they made it so they couldn’t manipulate each other and would therefore make both of them useless against each other. Update decides to make a deal with file aware and update brings back file aware’s Papyrus. In exchange Update and file aware now work as a duo and they help each other out if/when needed.
Update Sans likes Sleeping Ketchup Papyrus File Aware
If you couldn’t tell update sans can update any part of the code in an instant
Also I tried to see if this already existed and I found one with the same name but couldn’t find out anything about it. This is my first ever sans au. Feel free to ask any questions and I will try my best to answer them. Also if you’re wondering about phase, no one has ever gotten him to second phase bc he overpowered and new but said that he would try look kinda like ulb p3
Update: AddEd more abt the other aus he met also aus mentioned are not canon to their timeline (idk if I have to say that.)
